National Archives and Records Administration - DIMOC 803482 - THE WALKER SPY RING - LESSONS LEARNED - RETIRED NAVY WARRANT OFFICER JOHN WALKER AND OTHERS HAD BEEN CAUGHT DELIVERING NAVY SECRET MATERIAL TO THE SOVIETS. A CRIME THAT WAS COMMITTED FOR OVER SEVENTEEN YEARS. A CRIME WHOSE GLOBAL CONSEQUENCES ARE STILL BEING PROBED, AND SERIOUSLY JEOPARDIZED U.S. NAVAL PLANS AND OPERATIONS THAT STILL PUT AT RISK SOME OF THE MISSIONS THE U.S. NAVY IS CALLED UPON TO PERFORM. THE PEOPLE WHO COMMITTED THIS CRIME ARE NOW INCARCERATED IN A U.S. PENITENTIARY. THERE ARE ALWAYS LESSONS TO BE LEARNED SO THAT WHAT HAPPENED ONCE, WILL NOT HAPPEN AGAIN. THIS PRESENTATION IS INTENDED TO INFORM DEPARTMENT OF THE NAVY PERSONNEL ABOUT THE CIRCUMSTANCES OF ESPIONAGE IN THE WALKER/WHITWORTH CASE. HOPEFULLY, BY BEING MORE AWARE OF WHAT HAPPENED IN THIS CASE, DEPARTMENT OF THE NAVY PERSONNEL WILL BE BETTER PREPARED TO DETECT AND THWART SIMILAR INCIDENTS IN THE FUTURE. -
This is a Public Relations type film and really does not have much substance to it; nor is it partucularily interesting.
According to Wikipedia (take it for what it's worth) Walker enabled the Russians to decipher one million encrypted Naval messages. Enabled the Russians to track at all times all U.S. Naval Submarines. Told the Russians how the U.S. was able to track Russian Submarines so they could devise counter-measures. And so on and so forth.
After being arrested for burglary Walker was given the option of going to jail or enlisting in the Military. He enlisted in the Navy in 1955.
At 06:35 apparently that is a KL-7 "Adonis" Crypto Machine (?). Often used as back-up when radio propogation conditions were poor and would not allow electronic digital cryptographic machines to be used.
Dirk Rijmenant's Cipher Machines & Cryptology Site (Award Winning) has a KL-7 simulator as well as a wealth of information.
